Share an ASA Access Control List with Multiple ASA Devices

Sharing access policies in network security effectively improves efficiency, consistency, and centralized management, leading to an overall improved security posture. With a shared access control list, you can define access rules once on an ASA device and apply them to other Security Cloud Control-managed ASA devices rather than configuring them separately. This ensures consistency in the network and reduces the risk of misconfigurations. Additionally, shared access control lists provide scalability because networks grow and evolve by allowing you to manage access control lists for increasing users and ASA devices.

Keep the following points in mind:

  • Access control list rules are shared, but the interfaces are not included.

  • Sharing an access control list with other ASA devices will overwrite any existing access control lists with the same name.
